However if you leave the folder intact, whenever new features or patches are available, execute:
-`git pull; sudo make uninstall; sudo make distclean; ./autogen.sh; make -j<no. of cpu cores>; sudo make install`
+`git pull; sudo make uninstall; sudo make maintainer-clean; ./autogen.sh; make -j<no. of cpu cores>; sudo make install`
Only the changed sources are downloaded, which makes this a quick operation.
